Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537596, here are decompositions:

5 + 31537591 = 31537596
23 + 31537573 = 31537596
37 + 31537559 = 31537596
53 + 31537543 = 31537596
89 + 31537507 = 31537596
127 + 31537469 = 31537596
163 + 31537433 = 31537596
257 + 31537339 = 31537596

Showing the first eight; more decompositions exist.
